Abstract
Objective: To study the anti-fibrotic effect of ghrelin on high-fat diet-induced non-alcoholic steatohepatitis (NASH) in mice. Methods: 24 male C57BL/6 mice were randomly divided into a normal diet group, a normal diet + ghrelin group, a high-fat diet group, and the high-fat diet + ghrelin group. The HFD and HFD+ghrelin groups were fed high-fat diet for 16 weeks to induce non-alcoholic steatohepatitis. Among them, the NCD+ghrelin group and HFD+ghrelin group were continuously given ghrelin intervention (11nmol·kg(-1)·d(-1)) for 2 weeks after feeding for 14 weeks. 16 mice were euthanized on weekends. The plasma levels of alanine aminotransferase (ALT) and hyaluronic acid (HA) were measured in mice. The content of hydroxyproline (Hyp) was determined in liver tissue. RT-qPCR was used to detect the mRNA expression levels of transforming growth factor β1 (TGF-β1) and collagen types I, III, and IV in liver tissue. A Western blot was used to detect the expression level of the α-smooth muscle actin (α-SMA) protein in liver tissue. HE staining was used to observe the morphological changes in liver tissue. VG staining was used to observe the fibrotic condition in liver tissue. Results: Compared with the NCD group, plasma ALT (266.80±146.80)U/L, HA (219.00±39.47) ng/ml levels, Hyp content (0.35±0.05)μg/mg prot (P < 0.05), mRNA expression levels of transforming growth factor β1 (TGF-β1) and collagen types I, III, IV (P < 0.05), and the expression level of α-SMA protein in the HFD group were significantly increased (P < 0.05), with congestion in the hepatic central lobular veins, hepatocytes swelling, and deposition of a large amount of collagen fibers in liver tissue. Compared with the HFD group, plasma ALT (57.17±20.88)U/L, HA (75.68±8.40)μg/mg levels, Hyp content (0.19±0.07)μg/mg prot, mRNA expression levels of transforming growth factor β1 (TGF-β1) and collagen types I, III, IV (P < 0.05), and the expression level of α-SMA protein in the HFD+ghrelin mice group was significantly reduced (P < 0.05), with only mild sinusoidal congestion in the liver tissue but significant improvement and reduction in liver injury and collagen fiber deposition. Conclusion: Ghrelin has a significant improvement effect on liver fibrosis in NASH mice.

Abstract
OBJECTIVE This study aimed to investigate the causal associations between several liver traits (liver iron content, percent liver fat, alanine transaminase levels, and liver volume) and colorectal cancer (CRC) risk using a Mendelian randomization (MR) approach to improve our understanding of the disease and its management. METHODS Genetic variants were used as instrumental variables, extracted from genome-wide association studies (GWAS) datasets of liver traits and CRC. The Two-Sample MR package in R was used to conduct inverse variance weighted (IVW), MR Egger, Maximum likelihood, Weighted median, and Inverse variance weighted (multiplicative random effects) MR approaches to generate overall estimates of the effect. MR analysis was conducted with Benjamini-Hochberg method-corrected P values to account for multiple testing (P < 0.013). MR-PRESSO was used to identify and remove outlier genetic variants in Mendelian randomization (MR) analysis. The MR Steiger test was used to assess the validity of the assumption that exposure causes outcomes. Leave-one-out validation, pleiotropy, and heterogeneity testing were also conducted to ensure the reliability of the results. Multivariable MR was utilized for validation of our findings using the IVW method while also adjusting for potential confounding or pleiotropy bias. RESULTS The MR analysis suggested a causal effect between liver volume and a reduced risk of CRC (OR 0.60; 95% CI, 0.44-0.82; P = 0.0010) but did not provide evidence for causal effects of liver iron content, percent liver fat, or liver alanine transaminase levels. The MR-PRESSO method did not identify any outliers, and the MR Steiger test confirmed that the causal direction of the analysis results was correct in the Mendelian randomization analysis. MR results were consistent with heterogeneity and pleiotropy analyses, and leave-one-out analysis demonstrated the overall values obtained were consistent with estimates obtained when all available SNPs were included in the analysis. Multivariable MR was utilized for validation of our findings using the IVW method while also adjusting for potential confounding or pleiotropy bias. CONCLUSION The study provides tentative evidence for a causal role of liver volume in CRC, while genetically predicted levels of liver iron content, percent liver fat, and liver alanine transaminase levels were not associated with CRC risk. The findings may inform the development of targeted therapeutic interventions for colorectal liver metastasis (CRLM) patients, and the study highlights the importance of MR as a powerful epidemiological tool for investigating causal associations between exposures and outcomes.

Abstract
BACKGROUND/PURPOSE Alanine aminotransferase (ALT) is a cost-effective screening test for asymptomatic liver diseases. The aims of this study are to redefine the ULNs of ALT using the 2010-2012 Nutrition and Health Survey in Taiwan (NAHSIT) database and to determine whether the updated ULNs can better screen for metabolic dysfunction-associated fatty liver disease (MAFLD) in obese children. METHODS Reference data were obtained from 2895 NAHSIT participants (1442 boys, 1453 girls) aged 6-18 years. Participants with any of MAFLD-related metabolic risk factors, including overweight/obesity, elevated triglyceride, low high-density lipoprotein cholesterol and high fasting glucose, were excluded. This study compared the sensitivities of different ULNs of ALT for detecting MAFLD in our previously established cohort of obese children. RESULTS The ULNs of ALT defined as the 95th percentile in metabolically healthy NAHSIT participants were 23 IU/L for boys and 18 IU/L for girls. When using the updated ULNs, the percentages of elevated ALT levels were 13.0% in boys and 7.8% in girls of all NAHSIT participants. When using the updated ULNs of ALT to detect MAFLD in obese children, the sensitivity was 84.0% in boys and 74.3% in girls. In contrast, when using the conventional ALT cutoff (>40 IU/L), the sensitivity decreased to 61.4% in boys and 36.4% in girls. CONCLUSION After taking into account MAFLD-related metabolic risk factors, the ULNs of ALT are 23 IU/L for boys and 18 IU/L for girls in Taiwan. The updated ULNs may be better cutoffs for screening MAFLD in obese children.

Abstract
The saponins in different parts of Gynostemma pentaphyllum were analyzed via UPLC-Q-TOF-MS~E. A total of 46 saponins were identified, and the underground part had 26 saponins more than the aboveground part, most of which were trisaccharide saponins. The rat model of hyperlipidemia was established with high-fat diet. This study explored the lipid-lowering activity of total saponins in the underground part of G. pentaphyllum, so as to provide a theoretical basis for the comprehensive utilization of the underground part of G. pentaphyllum. A total of 99 healthy SD rats were randomly assigned into a blank group, a model group, a positive drug group, an aboveground total saponins group, and low-, medium-, and high-dose underground total saponins groups. Except the blank group, the other groups were fed with high-fat diet for 6 weeks. Then, the blood was collected from the orbital cavity to determine whether the modeling was successful according to the serum levels of total cholesterol(TC) and triglyceride(TG). After intragastric administration of the corresponding agents for 30 continuous days, the physical state of the rats were observed, and the body weight and liver specific gravity were measured. Furthermore, the levels of TC, TG, low-density lipoprotein cholesterol(LDL-C), high-density lipoprotein cholesterol(HDL-C), alanine transaminase(ALT), aspartate transaminase(AST), bilirubin, and total bile acids in serum, as well as the levels of superoxide dismutase(SOD), malondialdehyde(MDA), peroxidase proliferator-activated receptor(PPAR-γ) in the liver tissue, were determined. The pathological changes of liver was observed via HE staining. The results showed that the aboveground total saponins and medium-and high-dose underground total saponins can treat hepatocyte steatosis, lower TC, TG, LDL-C, ALT, AST, total bilirubin, MDA, and PPAR-γ levels, and increase HDL-C and SOD levels in the model rats. The effect tended to be more obvious with the increase in dosage. Therefore, the total saponins in the underground part of G. pentaphyllum have good pharmacological effect of reducing blood lipid, which provides a theoretical basis for the comprehensive utilization of the underground part of G. pentaphyllum.

Abstract
Monitoring the liver status in a convenient and low-cost way is significant for obtaining a warning about drug-indued liver diseases promptly. Herein, we designed a novel colorimetric point-of-care (POC) platform for the determination of three liver-related biomarkers─aspartate transaminase (AST), alanine transaminase (ALT), and alkaline phosphatase (ALP). This platform integrated agarose hydrogels into a portable device, where hydrogels were loaded with nanozymes and different reaction substances for triggering specific reactions and generating colorimetric signals. Typically, Au-decorated CoAl-layered double oxide (Au/LDO) was for the first time developed as the nanozyme with peroxidase (POD) mimic activity, which can accelerate the oxidation of colorless 3,3',5,5'-tetramethylbenzidine (TMB) to blue oxTMB with the coexistence of hydrogen peroxide (H2O2). The detection mechanism of AST and ALT is based on the fact that they can cause individual cascade reactions to generate H2O2, and H2O2 further activates the Au/LDO nanozyme to catalyze the chromogenic reaction of TMB. As for ALP, it can catalytically hydrolyze l-ascorbic acid-2-phosphate to ascorbic acid. The latter then discolored the oxTMB that was produced with the assistance of Au/LDO. Teaming up with a smartphone, the color information of hydrogels can be converted to hue values, which allow quantitative analysis of ALT, AST, and ALP with detection limits of 15, 10, and 5 U/L, respectively. Moreover, the simple and cost-effective platform was successfully applied for the simultaneous determination of the three analytes in human plasma. Additionally, since the hydrogel is disposable and can be replaced by new ones loaded with different reaction regents, the platform is expected to serve the POC testing of various chem/bio targets.

Abstract
BACKGROUND Sarcopenia and frailty influence clinical patients' outcomes. Low alanine aminotransferase (ALT) serum activity is a surrogate marker for sarcopenia and frailty. In-hospital hypoglycemia is associated, also with worse clinical outcomes. AIM We evaluated the association between low ALT, risk of in-hospital hypoglycemia and subsequent mortality. DESIGN This was a retrospective cohort analysis. METHODS We included patients hospitalized in a tertiary hospital between 2007 and 2019. Patients' data were retrieved from their electronic medical records. RESULTS The cohort included 51 831 patients (average age 70.88). The rate of hypoglycemia was 10.8% (amongst diabetics 19.4% whereas in non-diabetics 8.3%). The rate of hypoglycemia was higher amongst patients with ALT < 10 IU/l in the whole cohort (14.3% vs. 10.4%, P < 0.001) as well as amongst diabetics (24.6% vs. 18.8%, P < 0.001). Both the overall and in-hospital mortality were higher in the low ALT group (57.7% vs. 39.1% P < 0.001 and 4.3% vs. 3.2%, P < 0.001). A propensity score matching, after which a regression model was performed, showed that patients with ALT levels < 10 IU/l had higher risk of overall mortality (HR = 1.21, CI 1.13-1.29, P < 0.001). CONCLUSIONS Low ALT values amongst hospitalized patients are associated with increased risk of in-hospital hypoglycemia and overall mortality.

Abstract
Hepatitis D is the most severe form of human viral hepatitis and currently lacks an efficient therapy. Dendritic cell-derived exosomes (Dexs) have been found to induce immune responses capable of eliminating viruses. However, the therapeutic potential of antigen-loaded exosomes in hepatitis D is still unknown. Recently, we designed exosomes loaded with ubiquitinated hepatitis delta virus (HDV) small delta antigen (Ub-S-HDAg) and then treated mice bearing replicating HDV with these exosomes to explore their antiviral effect and mechanism. Mature dendritic cell-derived exosomes (mDexs) were loaded with Ub-S-HDAg and their antivirus function was evaluated in mice with HDV viremia. Furthermore, the proportion of CD8+ cells, the ratio of Th1/Th2 cells, the postimmunization levels of cytokines were explored, and the Janus kinases (JAK)/signal transducer and activator of transcription (STAT) pathway was evaluated with a JAK2 inhibitor AG490. In Ub-S-HDAg-Dexs group, the HDV RNA viral load was significantly decreased compared with other groups by CD8+ cell enrichment and an increase Th1/Th2 cell ratio. Furthermore, lymphocyte infiltration was increased, while the HDAg level was decreased in mouse liver tissue. However, there were no significant differences in HBV surface antigen (HBsAg), alanine aminotransferase (ALT), or aspartate aminotransferase (AST) levels among the groups. Moreover, p-JAK2, p-STAT1, p-STAT4, STAT1, and STAT4 expression was increased in Ub-S-HDAg-Dexs group. In conclusion, Ub-S-HDAg-Dexs might be a potential immunotherapeutic agent for eradicating HDV by inducing specific cellular immune response via the JAK/STAT pathway. IMPORTANCE Hepatitis D is the most severe viral hepatitis with accelerating the process of liver cirrhosis and increasing the risk of hepatocellular carcinoma. However, there are no effective antiviral drugs. Exosomes derived from mature dendritic cells are used not only as immunomodulators, but also as biological carriers to deliver antigens to induce robust immune response. Based on these properties, exosomes could be used as a biological immunotherapy by enhancing adaptive immune response to inhibit hepatitis D virus replication. Our research may provide a new therapeutic strategy to eradicate HDV in the future.

Abstract
BACKGROUND Visceral leishmaniasis (VL) is one of the major public health burden, mainly distributed throughout tropical and subtropical regions of the world. Among the Sub-Saharan African countries, Ethiopia is the second most affected country with VL. An Alteration of liver function is a typical manifestation of the disease. OBJECTIVE The purpose of conducting this study was to assess liver function tests and associated risk factors among VL patients at Leishmaniasis Research and Treatment Center of University of Gondar Comprehensive Specialized Hospital, North West Ethiopia. METHOD Hospital based comparative cross-sectional study design was conducted. A total of 102 study participants were involved in this study. Newly diagnosed VL patients who were attended at Leishmaniasis Research and Treatment Center of University of Gondar Comprehensive Specialized Hospital from 21st February 2020 to 30th September 2020 were included under case group category. On the other hand, age-sex matched apparently healthy study subjects were categorized as control group. Written consent was obtained willingness of patients to participate after ethical clearance was obtained from the Institutional Review Board of School of Medicine, University of Gondar. After overnight fasting, 5ml venous blood was drawn from both VL patients and controls to evaluate liver function tests, including AST, ALT, total bilirubin, albumin, and total protein. Thus, senior health professionals (laboratory technologist) investigate the results using Cobas Integra 400 Plus clinical chemistry analyzer. Data was entered into Epi-data version 4.6 and exported to STATA 14 for analysis of liver function tests and associated risk factors. RESULT The result of this study showed that significant mean difference was exhibited in aspartate aminotransferase (AST), alanine aminotransferase (ALT), total bilirubin, serum albumin, and total protein level among VL patients and controls. It showed that there was a statistically significant elevation in the level of AST, ALT, and total bilirubin among cases as compared to control. The serum AST level was significantly (p<0.001) elevated among cases as compared to controls. Serum ALT was significantly (p<0.001) elevated among cases compared to controls. Additionally, the total serum bilirubin level was significantly increased (P<0.001) among cases as compared to controls. There was a statistically significant (P<0.001) reduction of serum albumin level among VL patients as compared to controls. Similarly, serum total protein was significantly (P<0.001) reduced in VL patients than control groups. CONCLUSION There were significantly higher mean levels of serum AST, ALT, and total bilirubin among VL patients as compared to controls. On the other hand, VL patients showed significantly lowered level of albumin and total protein as compared to controls.

Abstract
Beta vulgaris L. is a vegetable most commonly consumed in salads and has been shown to possess multiple benefits. This research was carried out to observe the effects of Beta vulgaris powder at different doses orally in albino rabbits on liver biochemical parameters and coagulation. The study was carried out on albino rabbits which were divided into three groups designated as Group I (administered distilled water) Group II and III (administered beetroot powder at 500mg/kg and 1000mg/kg dose respectively) orally for 2 month duration. The sample was withdrawn at day 0, 30th and 60th day through cardiac puncture. The results showed that both doses of Beta vulgaris were considered safe for use as all the liver parameters were significantly decreased compared to control. Among both doses 500mg/kg dose was considered safer as it reduced the parameters significantly compared to 1000mg/kg dose. Blood coagulation factors at both the doses showed significant increase which was in reference range. Beta vulgaris is a highly beneficial dietary product with ample amount of flavonoids and anti-oxidant agents which might help in improving the liver function and also play a role in coagulation by increasing both fibrinogen levels and prothrombin time.

Abstract
BACKGROUND/AIMS The number of cases with coronavirus disease 2019 (COVID-19) has exceeded seven million worldwide. However, the data describing the global prevalence of liver injury associated with COVID-19 is lacking secondary to the novelty of this ongoing pandemic. Therefore, we conducted a meta-analysis to determine the association between COVID-19 and liver injury. METHODS A systematic literature search of indexed databases including, PubMed, Medline, and Embase databases from inception to 14 April 2020, was used to identify studies that reported data of liver chemistry in patients diagnosed with COVID 19. The overall prevalence of abnormal liver chemistry and relevant 95% confidence interval was used to estimate the pooled results studies. RESULTS Sixty-four studies with 11 245 patients with COVID-19 were included. The pattern of abnormal liver enzymes was notable for higher aspartate aminotransferase (AST) than alanine aminotransferase (ALT) levels. The overall global prevalence of elevated AST, ALT, total bilirubin, gamma-glutamyltransferase (GGT), and alkaline phosphatase was 23.2, 21.2, 9.7, 15.0, and 4.0%, respectively. The prevalence of elevated AST was substantially higher among those with severe cases (45.5%) compared to non-severe cases (15.0%). Co-existing chronic liver disease presented up to 37.6% of patients with COVID-19. CONCLUSION A fourth of COVID-19 patients had elevated liver enzymes and associated with disease severity. Our study may be used as a guide for clinicians and epidemiologists to proactively identify other sources of injury and illness in patients diagnosed with COVID-19. Intensive monitoring for liver injury may be needed in cases with severe COVID-19.

Abstract
INTRODUCTION Immune checkpoint inhibitors (ICIs), particularly anti-PD-1 antibody, have dramatically changed cancer treatment; however, fatal immune-related adverse events (irAEs) can develop. Here, we describe a severe case of sclerosing cholangitis-like irAE. We report the use of 3 immunosuppressive agents that resulted in the death of the patient due to treatment inefficacy. According to a postmarketing study of nivolumab, the frequency of ICI-related sclerosing cholangitis is 0.27% and that of ICI-related cholangitis is 0.20%. There have been 4 case reports of sclerosing cholangitis-like irAE, with imaging findings, including typical intrahepatic bile duct beaded constriction in primary sclerosing cholangitis. Treatment starts with prednisolone and is combined with an immunosuppressant in refractory cases. There are no reports of severe cases that ultimately led to death. PATIENTS CONCERNS The patient is a 64-year-old male with Stage IV squamous cell lung carcinoma; he was hospitalized with abdominal pain and elevation of aspartate transaminase and alanine transaminase, approximately 4 months after ICI administration was suspended. This occurred because the patient treated with nivolumab as the second-line chemotherapy and developed type 1 diabetes mellitus after 11 courses. DIAGNOSIS A grade 3 increase in bilirubin was observed and he was diagnosed with sclerosing cholangitis, based on magnetic resonance cholangiopancreatography imaging and pathological findings of the liver and bile duct. INTERVENTIONS Prednisolone, mycophenolate mofetil, and tacrolimus combination therapy was administered. OUTCOMES The treatment was difficult and failed. He died from liver failure 8 months after diagnosis. In this case, hepatitis and cholangitis, mainly alanine transaminase-dominant liver disorder, developed in the early stages of irAEs. Although he showed some improvement after prednisolone administration, bilirubin levels began rising again, and sclerosing cholangitis did not improve even with the use of 3 immunosuppressive agents recommended by the ESMO Clinical Practice Guidelines for immune-related hepatotoxicity management. Although the antitumor effect showed a complete response, liver failure led to death. CONCLUSION This is the first case report on the ineffectiveness of triple immunosuppressant combination therapy recommended by the guidelines for immune-related hepatotoxicity. It is necessary to develop more appropriate treatment for severe sclerosing cholangitis-like irAE based on the robust evidence.

Abstract
The novel coronavirus severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) is the causative agent of coronavirus disease 2019 (COVID-19). The presenting symptoms of this virus are variable, and there is an increasing body of literature on risk factors for mortality. The aim of this study was to evaluate the effect of initial aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels and preexisting liver disease, including cirrhosis, in a cohort of patients admitted with COVID-19 infection at a tertiary care hospital network in the Bronx, New York. We reviewed 3,352 patients who had a positive SARS-CoV2 nasal swab, were over 18 years of age, and had an associated inpatient admission and discharge (or death) to the Montefiore Medical Center from February 28, 2020, to May 22, 2020. Of these, 39/86 (45%) patients died when the initial ALT was >5 times the upper limit of normal (ULN); 115/230 (50%) patients died when the initial AST was >3 times the ULN. The mortality of patients without preexisting liver disease was 26.6% compared to a mortality rate of 29.5% in patients with liver disease. Subgroup analysis showed a mortality of 36.1% in the patients with cirrhosis. Cirrhosis conferred a hazard ratio for mortality of 1.67 (95% confidence interval, 1.09, 2.55; P = 0.019). The baseline Model for End-Stage Liver Disease score was not prognostic in the cirrhosis cohort. There was no statistical difference between mortality in patients with a history of compensated or decompensated cirrhosis. The most common cause of death in the cirrhosis cohort was respiratory failure. Conclusion: COVID-19 hepatitis may lead to poor outcomes in patients who are hospitalized for the disease. Patients with cirrhosis are at a higher risk of COVID-19-related mortality.

Abstract
BACKGROUND Nonalcoholic fatty liver disease (NAFLD) has emerged as a major health problem worldwide; according to statistics, 10% to 25% of patients with NAFLD can progress to nonalcoholic steatohepatitis (NASH). A link between the composition and metabolites of intestinal microbiota and the development of NAFLD is becoming clearer. It is believed that microbiota factors are driving forces of hepatic steatosis and inflammation. The formulated food that contains prebiotics and dietary fiber may improve NAFLD by altering the intestinal flora and its metabolites. METHODS The study plan to recruit adult patients (18-75 years, n = 120) with NAFLD, range of alanine aminotransferase is 1.5 to 5 times upper limit of normal (ULN) or liver biopsy is confirmed as NASH. Participants will be randomly allocated into 2 groups: formulated food (n = 80) and a placebo group (n = 40) for 24 weeks. Both groups will receive lifestyle and nutritional advice. The primary endpoint is a decrease in MRS-PDFF by more than 30% from baseline at 24 weeks. The secondary endpoints include the change of anthropometric, liver function, glycolipid metabolism, and systemic inflammation at 4, 12, and 24 weeks. In addition, we consider the changes in intestinal microbiota as an exploration to assess the abundance and diversity at 24 weeks. Weeks 24 to 36 are the follow-up period of drug withdrawal. DISCUSSION This clinical trial will provide evidence of efficacy and safety of formulated food as a potential new therapeutic agent for NAFLD patients. TRIAL REGISTRATION The trial is registered in the China Clinical Trial Center (ChiCTR1800016178).

Abstract
Colorectal cancer (CRC) is a common malignancy occurring in the digestive system. Despite progress in surgery and therapy options, CRC is still a considerable cause of cancer mortality worldwide. In this study, a colon cancer patient-derived xenograft model was established to evaluate the antitumor activity of Shikonin. The protective effect underlying Shikonin was determined through assessing serum levels of liver enzymes (ALT, AST) and kidney functions (BuN, Scr) in PDX mice. Proteomics and metabolomics profiles were integrated to provide a systematic perspective in dynamic changes of proteins and global endogenous metabolites as well as their perturbed pathways. A total of 456 differently expressed proteins (DEPs), 32 differently expressed metabolites (DEMs) in tumor tissue, and 20 DEMs in mice serum were identified. The perturbation of arginine biosynthesis, purine metabolism, and biosynthesis of amino acids may mainly account for therapeutic mechanism of Shikonin. Furthermore, the expression of mRNAs participating in arginine biosynthesis (CPS1, OTC, Arg1) and do novo purine synthesis (GART, PAICS, ATIC) were validated through RT-qPCR. Our study provides new insights into the drug therapeutic strategies and a better understanding of antitumor mechanisms that might be valuable for further studies on Shikonin in the clinical treatment of colorectal cancer.

Abstract
BACKGROUND Screening for elevated serum alanine aminotransferase (ALAT) can help identifying individuals at the risks of chronic and metabolic diseases, but blood collection is invasive and cannot be widely used for investigations. Considered as simple and inexpensive screening indices, individual characteristics and anthropometric measurements can be measured in a large crowd and may be important surrogate markers for ALAT levels. This study aimed to examine the diagnostic performance of individual characteristics and anthropometric parameters as predictive factors for discerning an elevated ALAT activity among Shenzhen children and adolescents. METHODS A school-based screening study was performed from 9 high schools in Shenzhen during February 2017 and June 2018. Receiver operating characteristic curve was used to examine the diagnostic performance of each variable for detecting elevated ALAT. RESULTS Altogether 7271 students aged 9-17 years were involved. The proportion of elevated ALAT greatly increased with increasing classification of BMI-z. By the sex-specific cut-offs for elevated ALAT (30 U/L boys; 19 U/L girls), BMI showed the highest area under the curve of 0.789 (95% CI 0.765-0.812) and followed by weight (0.779 [0.755-0.802]), BMI-z (0.747 [0.722-0.772]), height (0.622 [0.597-0.647]), and age (0.608 [0.584-0.632]), while height-z was not capable. With the cut-off of 67.8 kg for weight and 22.6 kg/m2 for BMI, the accuracy to identify elevated ALAT was 87.1% for weight and 82.9% for BMI. CONCLUSIONS The presence of elevated ALAT was more common in overweight or obese children and adolescents. BMI and weight had the superiority of detecting elevated ALAT, followed by BMI-z, height, and age.

Abstract
BACKGROUND Liver dysfunction has been widely reported in connection with anorexia nervosa (AN) but the pathogenesis of these alterations has never been fully understood despite reported theories about the presence of insulin resistance (IR) and non-alcoholic fatty liver disease (NAFLD). The aim of this study is to investigate if hypertransaminasemia in AN is linked to IR and NAFLD. METHODS Anthropometric data and laboratory exams of 34 patients and 34 controls were analyzed, including alanine-aminotransferase, aspartate-aminotransferase and homeostatic model assessment of insulin resistance (HOMA-IR) index. All subjects also underwent magnetic resonance imaging (MRI), ultrasonography (US), and transient elastography (TE). RESULTS Evidence of increased alanine aminotransferase in AN patients was confirmed in our sample together with a lower HOMA-IR index compared to controls. Positive results in US appeared in 16 patients vs none in controls (p = 0.0007); patients with liver parenchyma abnormalities in US were not different than normal-US patients in any of the studied variables. Only one patient showed non-alcoholic fatty liver disease in MRI while abnormal TE was found in four patients and never in controls. CONCLUSIONS Liver damage suggested by increased serum liver enzymes cannot be due to liver steatosis but potentially to a different liver disease (not identified by MRI) or to an early liver fibrosis not associated with an insulin-resistant status.

Abstract
RATIONALE Procalcitonin (PCT) is used as a biomarker for identifying the occurrence of sepsis. Previous studies have reported high levels of PCT with acetaminophen intoxication without evidence of infection. Here, we report two patients with acetaminophen intoxication with high levels of PCT without showing any symptoms of bacterial infection. PATIENT CONCERNS This case study examined two unrelated patients with acetaminophen intoxication admitted to emergency at different times. The first patient was admitted to the emergency department after ingesting approximately 8000 mg (153.8 mg/kg) of acetaminophen. On admission, C-reactive protein (CRP), glutamic oxaloacetic transaminase (GOT), and glutamic pyruvic transaminase (GPT) were normal. PCT and acetaminophen levels were 31.89 ng/mL and below 0.5 μg/mL, respectively. The second patient was admitted to the emergency department 8 h after ingesting ∼23,600 mg (280.6 mg/kg) of acetaminophen. By the second day of admission, GOT and GPT increased to 2508 and 1473 IU/L, respectively. PCT was 45.66 ng/mL with acetaminophen level at 116.9 μg/mL. Both patients were clear of symptoms associated with bacterial infection. DIAGNOSIS Acetaminophen intoxication. INTERVENTIONS N-acetylcysteine was given intravenously to both patients for 20 h per protocol. OUTCOMES Both patients were discharged without complications. LESSONS Observations suggests that elevated levels of PCT in patients intoxicated with acetaminophen may be associated with involvement of other organs impacted by cytokine stimuli from sterile inflammation resulting from hepatic damage rather than PCT secretion directly caused by hepatic cell damage.

Abstract
PURPOSE To evaluate that Connexin (Cx43) plays a role in lesions after hepatic ischemia/reperfusion (IR) injury. METHODS We use Cx43 deficient model (heterozygotes mice) and compared to a wild group. The groups underwent 1 hour ischemia and 24 hours reperfusion. The heterozygote genotype was confirmed by PCR. We analyzed the hepatic enzymes (AST, ALT, GGT) and histology. RESULTS The mice with Cx43 deficiency showed an ALT mean value of 4166 vs. 307 in the control group (p<0.001); AST mean value of 7231 vs. 471 in the control group (p<0.001); GGT mean value of 9.4 vs. 1.7 in the control group (p=0.001); histology showed necrosis and inflammation in the knockout group. CONCLUSIONS This research demonstrated that the deficiency of Cx43 worses the prognosis for liver injury. The topic is a promising target for therapeutics advancements in liver diseases and procedures.

Abstract
OBJECTIVE The association between unbalanced iron indices and the conditions of schizophrenia are not well understood. Liver dysfunction which has been linked to iron metabolism might be a contributing factor. This case-control study evaluated serum iron indices and liver function in treatment-naïve schizophrenia patients and those already on treatment at the Psychiatric Department of the Komfo Anokye Teaching Hospital (KATH), Kumasi-Ghana. RESULTS The mean age of the respondents was 39.6 ± 0.8 years. Increased levels of serum iron, TS, AST, ALT and AST:ALT ratio and lower levels of UIBC, TIBC, Transferrin, and log Ferritin:AST ratio levels were observed among the treatment-naïve group compared to the control. The treatment-naïve and treatment groups showed significantly higher serum AST:ALT ratio, and lower log10ferrtin:AST ratio than the healthy controls. There was a significant correlation between log10ferritin and AST, and log10ferritin and GGT in both treatments (r = 0.343; p = 0.003, and r = 0.502; p = 0.001 respectively) and treatment-naïve groups (r = 0.348; p = 0.002, and r = 0.614; p < 0.001 respectively). Percentage transferrin saturation correlated significantly with GGT only, in the treatment-naïve group (r = 0.667; p < 0.001), and ALT and GGT in the treatment group (r = 0.252; p = 0.030 and r = 0.646; p = 0.014 respectively).

Abstract
This research investigated the protective effect of lactobacillus plantarum against alcohol-induced liver injury and the regulatory mechanism of Keap-Nrf2-ARE signal pathway in zebrafish. Firstly, a zebrafish alcoholic liver injury model was established using1.0mM of ethanol concentration, then two forms of lactobacillus plantarum treatment were designed to perform repair, including a lactobacillus plantarum thallus suspension (LPS) and a lactobacillus plantarum thallus breaking solution (LPBS). After 24h of alcohol injury, lactobacillus plantarum concentrations of 0, 1.0×105, 1.0×106, 1.0×107 and 1.5×107 cfu/mL were added to protect zebrafish larvae. Then with the treatment of lactobacillus plantarum after 48h, activities of alanine transaminase (ALT), aspartate transaminase (AST), superoxide dismutase (SOD) and malondialdehyde (MDA) in zebrafish tissue homogenate were respectively determined. Keap-Nrf2-ARE signal pathway related gene expression conditions were also analyzed, including nuclear factor (erythroid-derived 2)-like 2(Nrf2), Kelch like ECH associated protein 1(Keap1), catalase(CAT), hemooxygenase1(HO1) and Glutathione S-Transferase Kappa 1(gstk1). Results showed that: in comparison with the control group, the LPBS with dosage of 1.0×107 cfu/mL remarkably improved the activities of SOD, CAT, HO1and gstk1 in zebrafish larvae liver (P<0.05), resulting in significant increase of the protein expression level of Nrf2 (225.78%) and suppression of Keap1 gene expression (73.67%)(P<0.01). As confirmed by the results, lactobacillus plantarum activated the Keap-Nrf2-ARE signal pathway from the level of transcription, the up-regulation of the expression quantity of Nrf2 protected the organism from oxidative stress and maximally reduced liver injury.

Abstract
BACKGROUND Liver disease in patients with HIV is common and typically has complex and multifactorial presentations that represent a major cause of morbidity and mortality. Autoimmune hepatitis (AIH) is rarely reported in patient with HIV and the disease course and clinical outcomes for treatment have not been well characterized. We are aiming to determine the patient characteristics, disease prevalence, and treatment outcomes from published articles of patients with HIV and AIH. METHOD A systematic search of PubMed, Web of Science, and Google Scholar through February 20, 2019 identified 15 studies that reported the outcomes of AIH in patients with HIV. Because of the small sample sizes and skewed distributions, resampling tests of mean differences using permutation distributions (MAXn = 10,000 permutations) were utilized; analyses were performed using R (v. 3.5.1). Categorical differences were calculated using Fisher exact test for odds ratio = 1 (equal odds), and Cramer V was calculated for effect size; analyses were completed in SPSS (v. 25). RESULTS By reviewing 15 studies reporting a total of 35 patients with AIH and HIV, male patients were found to have significantly higher aspartate transaminase and alanine transaminase levels at time of diagnosis. No other significant findings identified. The CD4 count and viral load did not show significant correlation with AIH diagnosis or its prognosis. All patients but one who presented with severe immune deficiency and responded to highly active anti-retroviral therapy received immunosuppressive treatment without side effects and achieved remission except 2 lost to follow-up and 3 expired. CONCLUSION Although rare, but AIH can develop in patients with HIV and physicians should consider it in the differential diagnosis for HIV patients presented with abnormal liver function tests, especially after excluding hepatitis C virus and drug-induced liver injury.Patients with immune deficiency disorders who present with AIH can be treated safely with steroid either as monotherapy or in combination with another immune suppressant therapy.

Abstract
Nonalcoholic fatty liver disease (NAFLD) is the most prevalent cause of chronic liver disease worldwide. NAFLD is considerably more frequent in patients with type 2 diabetes mellitus (T2DM) than in the general population and is also more severe histologically in this group. Sodium-glucose co-transporter-2 (SGLT2) inhibitors, the newest class of antidiabetic agents, appear to represent a promising option for the management of NAFLD in patients with T2DM. In a number of studies, treatment with SGLT2 inhibitors resulted in a reduction in hepatic steatosis and in transaminase levels. However, existing studies are small, their follow-up period was short and none evaluated the effects of SGLT2 inhibitors on liver histology. Accordingly, larger studies are needed to verify these preliminary results and define the role of SGLT2 inhibitors in the treatment of NAFLD in patients with T2DM.

Abstract
Background and objectives: Boxing is a popular combat sport that requires high intensity and cooperation. However, there are limited data about the influence of boxing matches on blood parameters. The purpose of the present study was to investigate the match-induced changes in the metabolic, hormonal, and inflammatory status in male elite boxers. Materials and methods: High-level 20 male boxers with more than 5 years experience in boxing voluntarily participated in this study. Venous blood samples of the boxers, before and after combat, were taken for determination of the plasma parameters. Results: Our results indicated that a 9-min boxing match caused significant increases in plasma energy fuels (glucose and lactate), metabolic hormones (insulin, adrenocorticotropic hormone (ACTH), cortisol, and growth hormone), inflammatory markers (interleukin-1β (IL-1β), interleukin-6 (IL-6) and tumor necrosis factor alpha (TNF-α)), muscle damage indicators (alanine aminotransferase (ALT) and aspartate aminotransferase (AST)), and oxidative stress marker (SOD). A decrease in total oxidant status (TOS) was also considered. However, there were no significant alterations in the plasma levels of androgenic hormone (free and total testosterone), anabolic hormone (IGF-1), lipids (total cholesterol, triglyceride, high-density lipoprotein (HDL), and low-density lipoprotein (LDL)), kidney function markers (creatinine and urea), and minerals (iron (Fe) and magnesium (Mg)). Conclusion: Elevations in the level of energy fuels and metabolic hormones of the boxers could be taken as a reflection of high-energy turnover during combat performance. The increases in inflammatory and tissue damage indicators may possibly be an indication of traumatic injury. Understanding the biochemical changes that occur during boxing match could be valuable to optimize the performance improvement of the athletes.

Abstract
AIMS Periodontitis results from the presence of periodontopathogenic bacterial activity in the region of the gingival sulcus promoting tissue degradation and alveolar bone resorption. Biochemical analysis of the saliva can be used as a less invasive method for disease prognosis. This study aimed to evaluate the relationship between biochemical protein levels in the saliva sample of patients with chronic periodontitis and healthy patients. MATERIALS AND METHODS A literature review was performed using electronic databases (Cochrane Library, Google Scholar, MEDLINE, PubMed, and Web of Science) for studies published before July 2, 2016. The abstracts were evaluated, and the data extraction was performed by two calibrated examiners. The mean difference, and heterogeneity were calculated, and funnel plots were produced. RESULTS Twenty case-control studies were selected with 2436 patients with chronic periodontitis and 1787 controls. The meta-analysis showed that increased levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), creatine kinase (CK), lactate dehydrogenase (LDH), alkaline phosphatase (ALP), and acid phosphatase (ACP) were all associated with periodontitis (p < 0.05), while blood urea nitrogen (BUN) and osteoprotegerin (OPG) levels did not show statistical differences between cases and controls (p > 0.05). CONCLUSIONS This meta-analysis evidenced that increased levels of AST, ALT, CK, gama glutamil transferase (GGT), LDH, ALP, and ACP are associated in patients with chronic periodontitis, while BUN and OPG level in saliva did not present differences between groups.

Abstract
BACKGROUND Liver diseases have been bound to environmental factors, inclusive of air pollution. The exposure of workers to petrochemicals counts as a possible cause of Liver diseases, whereas results are inconsistent with the previous studies. In this study, a meta-analysis is conducted to assess the pooled risk. METHODS AND FINDING A systematic search was performed by related researchers. Correlations are analyzed among petroleum and liver cirrhosis mortality, fatty liver, alanine amino transferase (abbreviated as ALT), aspartate amino transferase (abbreviated as AST). Pooled risk ratios (RR) with 95% confidence interval (CI) and effect size(ES) with 95% confidence interval are calculated. Sensitivity analysis and publication bias are also tested. Data are analyzed from 5 studies involving 296 participants. Results are incorporated through adopting a random effects meta-analysis. Working in a petrochemical plant shall not increase the death risk posed by cirrhosis (RR = 0.44, 95% CI [0.36; 0.54]). Yet the incidence of fatty liver increases (RR = 1.22, 95% CI [1.21; 1.23]). Abnormal incidence of ALT and AST also increases. CONCLUSIONS Occupational exposure plays an important role in causing ALT abnormalities and fatty liver among oil workers, but not a risk factor of cirrhosis, AST abnormalities and liver cancer.

Abstract
OBJECTIVE To establish an ex vivo model of myocardial ischemia reperfusion in tree shrews. METHODS The Langendorff ex vivo heart perfusion system was used to establish the myocardial ischemia reperfusion model in tree shrews with different irrigation and reperfusion time settings. Alanine aminotransferase (ALT), aspartate transaminase (AST) and lactic dehydrogenase (LDH) levels were measured by enzyme-labeled immunosorbent assay, creatine kinase MB (CK-MB) was detected using immunosuppression method, and malondialdehyde was measured with thiobarbital staining method; the infarct size was measured using 2, 3, 5-triphenyltrazoliumchloride (TTC) method. RESULTS Ischemia for 30 min and reperfusion for 30 and 60 min caused more significant increase in CK-MB and LDH levels in the perfusion fluid and also in the levels of ALT, CK-MB and AST in the myocardial tissue compared with other experimental settings (P<0.05), but these parameters were comparable between the former two settings (P>0.05). The mean heart rate in 30-min ischemia with 60-min reperfusion group was obviously lower than that in continuous reperfusion group, 15-min ischemia with 30-min reperfusion group and 30-min ischemia with 30-min reperfusion group (P<0.05), and the heart rate was similar between the latter 3 groups (P>0.05). ECG analysis showed that the mean heart rate in 30-min ischemia with 30-min reperfusion group was closer to the physiological heart rate of tree shrews. CONCLUSION We successfully established an ex vivo myocardial ischemia reperfusion model using tree shrews, and ischemia for 30 min followed by reperfusion for 30 min is the optimal experimental setting.

Abstract
We have developed a new system for direct xenogenic hemoperfusion of a bioartificial liver support system adopting two types of immunoadsorbent devices. In this study, we compared the efficacy of each immunoadsorbent device in maintaining porcine hepatocyte function during 3 h perfusion treatment in a canine liver failure model. Suppression of humoral immunity by the immunoglobulin adsorber prevented immunogenic hepatocyte injury more effectively, and the system showed higher hepatic function when compared with suppression of cell-mediated immunity by the leukocyte adsorber. However, single use of immunoglobulin adsorber was less effective in reducing patients' systemic ammmonia levels and modulating the Fischer's ratio compared with the case of combined use of both immunoadsorbent devices. These results suggest that suppression of humoral immunity was of primary importance in preventing immunogenic hepatocyte injury, however the adsorption of leukocytes may have a synergic effect on maintaining hepatocyte function in direct xenogenic hemoperfusion.

Abstract
AIM To compare the effect of University of Wisconsin (UW) solution with or without metformin, an AMP-activated protein kinase (AMPK) activator, for preserving standard and marginal liver grafts of young and aged rats ex vivo by hypothermic machine perfusion (HMP).
METHODS Eighteen young (4 mo old) and 18 aged (17 mo old) healthy male SD rats were selected and randomly divided into three groups: control group, UW solution perfusion group (UWP), and UW solution with metformin perfusion group (MUWP). Aspartate aminotransferase (AST), alanine aminotransferase (ALT), lactate dehydrogenase (LDH), interleukin-18 (IL-18), and tumor necrosis factor-alpha (TNF-α) in the perfused liquid were tested. The expression levels of AMPK and endothelial nitric oxide synthase (eNOS) in liver sinusoidal endothelial cells were also examined. Additionally, microscopic evaluation of the harvested perfused liver tissue samples was done.
RESULTS AST, ALT, LDH, IL-18 and TNF-α levels in the young and aged liver-perfused liquid were, respectively, significantly lower in the MUWP group than in the UWP group (P < 0.05), but no significant differences were found between the young and aged MUWP groups. Metformin increased the expression of AMPK and eNOS protein levels, and promoted the extracellular release of nitric oxide through activation of the AMPK-eNOS mediated pathway. Histological examination revealed that in the MUWP group, the extent of liver cells and tissue damage was significantly reduced compared with the UWP group.
CONCLUSION The addition of metformin to the UW preservative solution for ex vivo HMP can reduce rat liver injury during cold ischemia, with significant protective effects on livers, especially of aged rats.

Abstract
Objective To investigate the protective effect of fisetin (FIS) against hypoxia/reoxygenation (H/R) injury in rat hepatocytes and its mechanism. Methods H/R injury model of BRL-3A cells was established and the cells were pretreated with FIS. Survival rate was detected by CCK-8 assay. Cell apoptosis was measured by flow cytometry. The levels of ALT and AST were determined by microplate assay. The production of TNF-α and IL-1β were detected by ELISA. The mRNA and protein levels of TLR4 and NF-κBp65 were analyzed by quantitative real-time PCR and Western blotting, respectively. Results After subjected to H/R, cell survival rate decreased and the apoptosis level increased. The levels of ALT and AST in cell supernatant were elevated, so were the production of TNF-α and IL-1β. FIS pretreatment increased the cell survival rate and inhibited apoptosis. The levels of ALT, AST and the production of TNF-α and IL-1β were reduced significantly. Moreover, FIS inhibited the increasing expression levels of TLR4 and NF-κBp65 induced by H/R. Conclusion FIS alleviates the hepatocyte injury induced by H/R via modulation of TLR4/NF-κB signaling pathway.

Abstract
BACKGROUND Sustained abnormal serum alanine aminotransferase (ALT) levels can increase the risk of hepatocellular carcinoma (HCC) in patients with chronic hepatitis B. AIM This study is aimed to confirm the impact of rapid ALT normalization (≤30 IU/L) on HCC risk in patients with hepatitis B virus (HBV)-associated cirrhosis after entecavir (ETV) commencement. METHODS A total of 578 treatment-naïve patients with HBV-associated cirrhosis (mean age 51 ± 9 years, male sex 63.3%) were treated with ETV for more than 1 year. Serum ALT and HBV DNA levels were measured at three time points (baseline, 6, and 12 months after ETV commencement) and subjected to risk factor analysis. RESULTS Median follow-up after ETV commencement was 43 (12-98) months. Cumulative incidences of HCC at 1, 3, 5, and 7 years were 0.3, 8.5, 19.5, and 30.6%, respectively. Univariate Cox regression analysis showed that older age, abnormal ALT at 6 months or 12 months, and lower platelet count were significant risk factors for HCC. However, gender, HBeAg positivity, abnormal ALT levels or HBV DNA levels at baseline, and detectable HBV DNA at 6 or 12 months were not risk factors. Multivariate analysis showed that older age (P < 0.001), abnormal ALT at 12 months (P = 0.006), and lower platelet count (P = 0.034) were the risk factors for HCC. CONCLUSIONS Abnormal serum ALT levels after ETV commencement are significant risk factor for HCC. Therefore, ALT should be rapidly normalized to minimize the risk of HCC development in patients with HBV-associated cirrhosis.

Abstract
Although liver function test abnormality is frequently noted in children, there is no report about the distribution of the etiology and natural recovery time of the abnormal liver function. From March 2005 to February 2014, clinical information was retrospectively collected from 559 children who had abnormal liver function and were hospitalized or visited the outpatient clinic at the Jeju National University Hospital. The etiology of abnormal liver function was classified into groups and the natural recovery time of abnormal liver function was analyzed. The etiological groups of 559 patients included 'nonspecific hepatitis' in 42 (7.5%), 'infection' in 323 (57.8%), 'rheumatologic and autoimmune' in 66 (11.8%), 'nonalcoholic fatty liver disease' in 57 (10.2%), 'anatomic' in 12 (2.1%), 'toxic' in 13 (2.1%), 'metabolic' in 8 (1.4%), 'hematologic' in 7 (1.3%), 'hemodynamic' in 4 (0.7%), and 'others' in 27 (4.8%). Among the 'infection' group (57.8%), the 'viral infection in the respiratory tract' subgroup, which had 111 patients (19.8%), was the most common. The natural recovery time of the abnormal liver function was 27 days (median) in 'nonspecific hepatitis', 13 days (median) in 'viral respiratory tract disease', 16 days (median) in 'viral gastroenteritis', 42 days (median) in 'viral febrile illness", and 7 days (median) in "Kawasaki disease". The information on the natural recovery time of abnormal liver function may help the physician to perform good clinical consultation for patients and their parents.

Abstract
BACKGROUND Noninvasive assessment of liver fibrosis has important clinical significance. Different techniques including two-dimensional shear-wave elastography (2D SWE) and real-time tissue elastography (RTE) are reported to be useful for the noninvasive diagnosis of hepatic fibrosis. All these techniques are affected by many factors. How to choose a reasonable method needs further studies. PURPOSE This study was conducted to comparatively assess the diagnostic performance of 2D SWE and RTE in patients with Chronic Hepatitis B (CHB) and influence of inflammation on the stiffness values obtained by both techniques, so as to objectively assess the reasonable choice between these 2 elastography techniques for noninvasive assessment of hepatic fibrosis in clinical practice. MATERIALS AND METHODS Four-hundred and thirty-seven patients with CHB meeting the inclusion criteria were enrolled in the study. All patients underwent liver stiffness measurements by using 2D SWE and RTE on the same day. Histologic fibrosis was staged and inflammation activity was graded based on the METAVIR scoring system on liver biopsy specimens. RESULTS The liver stiffness values by using 2D SWE and RTE both increased in parallel with the degree of liver fibrosis and the grade of inflammation. However, the diagnostic efficacy of significant fibrosis and cirrhosis using 2D SWE was significantly higher than that of RTE. The 2D SWE measurement values were statistically different in different alanine aminotransferase (ALT) levels and METAVIR activity grades; however, no statistically significant differences were observed by using RTE. The diagnostic efficacy of 2D SWE significantly varied with elevated ALT levels compared with RTE. CONCLUSION 2D SWE was more accurate than RTE in the assessment of significant fibrosis and cirrhosis in patients with CHB. Compared with RTE, the measurement values and diagnostic performance obtained by 2D SWE were prone to be more easily affected by the inflammation fluctuations.

Abstract
Lactic acidosis (LA), a rare but life-threatening adverse effect associated with antiretroviral therapy, has been reported with an increasing frequency since the mid1990s. From June 1994 to June 2002, a total of six patients, four males and two females with a median age of 43 years (range, 30 to 74 years), had been diagnosed with LA. The estimated incidence of LA was 5.1 per 1000 patient-years (PYs) on highly active antiretroviral therapy (HAART) (95% confidence interval [95% CI], 4.5-5.5 per 1000 PYs) and 4.4 per 1000 PY on nucleoside analogues (NAs) (95% CI, 3.9-4.7 per 1000 PYs). Their median body mass index at diagnosis of LA was 17.6 kg/m2 (range 16.3 to 22.6 kg/m2). The median CD4+ lymphocyte count at the initial diagnosis of HIV infection and at the onset of LA was 38 cells/µL (range, 4 to 103 cells/µL) and 108 cells/µL (range, 79 to 224 cells/µL), respectively. The most common symptoms were nausea, vomiting, and dyspnoea. All of the patients had findings suggestive of NA-related mitochondrial toxicity, such as myositis, pancreatitis, fatty hepatitis, peripheral neuropathy or lipodystrophy. The prescribed NA related to LA were stavudine in six patients, lamivudine, five, and didanosine, one. Despite treatment, all patients died of persistent circulatory collapse following LA. The median duration from diagnosis to death was eight days (range, 4-17 days). Our report highlights that clinicians caring for patients with AIDS should be alerted to the potentially fatal LA associated with antiretroviral therapy when patients present with low body mass index, lipodystrophy, unexplained abdominal symptoms, dyspnoea, or elevated aminotransferases.

Abstract
Hepatic reperfusion injury represents a crucial problem in several clinical situations including liver transplantation, extensive hepatectomy and hypovolemic shock with resuscitation. Repertaxin is a new non-competive allosteric blocker of interleukin-8 (CXCL8) receptors, which by locking CXCR1/R2 in an inactive conformation, prevents receptor signaling and polymorphonuclear leukocyte (PMN) Chemotaxis. The present study shows that repertaxin dramatically prevents rat post-ischemic hepatocellular necrosis (80% of inhibition) and PMN infiltration (96% of inhibition) at a clinically-relevant time (24 h) of reperfusion. Treatment with repertaxin by continuous infusion is demonstrated to be the optimal route of administration of the compound especially in view of its clinical threrapeutic use. Because repertaxin has proven to be safe and well tolerated in different animal studies and in phase I studies in human volunteers, it is in fact a candidate novel therapeutic agent for the prevention and treatment of hepatic post-ischemic injury.

Abstract
In this study, a miniaturized biosensor based on permselective polymer layers (overoxidized polypyrrole (Ppy) and Nafion®) modified and enzyme (glutamate oxidase (GlutOx)) immobilized micro-platinum wire electrode for the detection of alanine aminotransferase (ALT) was fabricated. The proposed ALT biosensor was measured electrochemically by constant potential amperometry at +0.7 V vs. Ag/AgCl. The ALT biosensor provides fast response time (~5 s) and superior selectivity towards ALT against both negatively and positively charged species (e.g., ascorbic acid (AA) and dopamine (DA), respectively). The detection range of the ALT biosensor is found to be 10–900 U/L which covers the range of normal ALT levels presented in the serum and the detection limit and sensitivity are found to be 8.48 U/L and 0.059 nA/(U/L·mm2) (N = 10), respectively. We also found that one-day storage of the ALT biosensor at −20 °C right after the sensor being fabricated can enhance the sensor sensitivity (1.74 times higher than that of the sensor stored at 4 °C). The ALT biosensor is stable after eight weeks of storage at −20 °C. The sensor was tested in spiked ALT samples (ALT activities: 20, 200, 400, and 900 U/L) and reasonable recoveries (70%~107%) were obtained.

Abstract
BACKGROUND To evaluate the prognostic significance of preoperatively assessed aspartate aminotransaminase (AST), alanine aminotransaminase (ALT), and the AST/ALT (De Ritis) ratio in patients with upper urinary tract urothelial carcinoma (UUTUC). METHODS This study included a total of 109 consecutive patients with clinically localized UUTUC who underwent nephroureterectomy. Effects of preoperative levels of AST, ALT, and the De Ritis ratio in addition to conventional clinicopathological parameters on the extravesical recurrence-free survival (eRFS) in these 109 patients were retrospectively analyzed. RESULTS Despite the lack of a significant correlation of AST or ALT with any of the factors examined in this study, the elevation of the De Ritis ratio was significantly correlated with several unfavorable parameters, including elderly age, high pathological stage, high tumor grade, and lymphovascular invasion. During the observation period of this series (median = 40.8mo), extravesical disease recurrence developed in 39 (35.8%) of the 109 patients, with a 5-year eRFS rate of 56.8%. Of several factors examined, the tumor location, De Ritis ratio, pathological stage, lymph node metastasis, tumor grade, lymphovascular invasion, surgical margin status, and adjuvant chemotherapy were shown to be significantly correlated with eRFS by univariate analysis. Of these, the De Ritis ratio, pathological stage, lymph node metastasis, and tumor grade were identified as independent predictors of eRFS on multivariate analysis. CONCLUSIONS These findings suggest that preoperative assessment of the De Ritis ratio may provide useful information with respect to the clinical course of patients with clinically localized UUTUC who are scheduled to be treated with nephroureterectomy.

Abstract
BACKGROUND Biological variation (BV) data enable assessment of the significance of changes in serial measurements observed within a subject and are used to set analytical quality specifications. This data is available in a database held in Westgard website (http://www.westgard.com/biodatabase1.htm). Some limitations of this data, however, have been identified in recent published reviews. The aim of this paper is to show the reliability of the published BV data and to identify ongoing works to address some of its limitations. METHODS The BV data currently hosted on the Westgard website was examined. Distribution of measurands stratified by the number of cited references upon which the database entry is based and the distribution of papers stratified by publication year, are shown. Moreover, BV data available in literature for glycated hemoglobin, C-reactive protein, glycated albumin, alanine aminotransferase, aspartate aminotransferase and γ-glutamyl transferase are evaluated. RESULTS The results obtained show that most BV data come just from a few papers or only one paper and that a lot of publications are dated, therefore this data is too obsolete to be used. Furthermore critical review of the BV database highlights a number of factors that might impact on the reliability of the BV data entries and translation into current practice. CONCLUSIONS A number of issues clearly undermine the value of the current database. These issues are being considered by the European Federation of Clinical Chemistry and Laboratory Medicine, biological variation working group, in collaboration with a Spanish group responsible for the database updating.

Abstract
PURPOSE Recent studies have revealed close relationships between hepatic injury, metabolic pathways, and gut microbiota. The microorganisms in the intestine also cause irritable bowel syndrome (IBS). The aim of this study was to examine whether IBS was associated with elevated hepatic enzyme [alanine aminotransferase (ALT) and aspartate aminotransferase (AST)], gamma-glutamyl transferase (γ-GT) levels, and metabolic syndrome (MS). MATERIALS AND METHODS This was a retrospective, cross-sectional, case-control study. The case and control groups comprised subjects who visited our health promotion center for general check-ups from June 2010 to December 2010. Of the 1127 initially screened subjects, 83 had IBS according to the Rome III criteria. The control group consisted of 260 age- and sex-matched subjects without IBS who visited our health promotion center during the same period. RESULTS Compared to control subjects, patients with IBS showed significantly higher values of anthropometric parameters (body mass index, waist circumference), liver enzymes, γ-GT, and lipid levels. The prevalences of elevated ALT (16.9% vs. 7.7%; p=0.015) and γ-GT (24.1% vs. 11.5%; p=0.037) levels were significantly higher in patients with IBS than in control subjects. A statistically significant difference was observed in the prevalence of MS between controls and IBS patients (12.7% vs. 32.5%; p<0.001). The relationships between elevated ALT levels, MS, and IBS remained statistically significant after controlling for potential confounding factors. CONCLUSION On the basis of our study results, IBS may be an important condition in certain patients with elevated ALT levels and MS.

Abstract
BACKGROUND Diagnosing hepatic injury in HIV infection can be a herculean task for clinicians as several factors may be involved. In this study, we sought to determine the effects of antiretroviral therapy (ART) and disease progression on hepatic enzymes in HIV patients. METHODS A case-control study conducted from January to May 2014 at the Akwatia Government Hospital, Eastern region, Ghana, The study included 209 HIV patients on ART (designated HIV-ART) and 132 ART-naive HIV patients (designated HIV-Controls). Data gathered included demography, clinical history and results of blood tests for hepatic enzymes. We employed the Fisher's, Chi-square, unpaired t-test and Pearson's correlation in analysis, using GraphPad Prism and SPSS. A P value < 0.05 was considered significant. RESULTS Median CD4 lymphocyte count of HIV-ART participants (604.00 cells/mm3) was higher than that of HIV-Controls (491.50 cells/mm3; P = 0.0005). Mean values of ALP, ALT, AST and GGT did not differ between the two groups compared (P > 0.05). There was a significant positive correlation between hepatic enzymes (ALP, ALT, AST and GGT) for both groups (p < 0.01 each). Duration of ART correlated positively with ALT (p < 0.05). The effect size of disease progression on hepatic enzymes for both groups was small. CONCLUSION Antiretroviral therapy amongst this population has minimal effects on hepatic enzymes and does not suggest modifications in therapy. Hepatic injury may occur in HIV, even in the absence of ART and other traditional factors. Monitoring of hepatic enzymes is still important in HIV patients.

Abstract
A 61-year-old male patient was admitted because of unexplained abdominal pain and anemia. His past medical history was unremarkable except for having taken herbal medicine to treat facial palsy two months ago. The result of health examination performed about a month ago showed increased serum aspartate and alanine aminotransferase level, and he was diagnosed with toxic hepatitis by herbal medicine. When the patient presented to the outpatient department three weeks ago, follow-up liver function test results showed improvement but he complained of abdominal pain. Despite extensive blood chemistry tests and computed tomography, the cause of pain could not be found. After much deliberation, serum lead level and herbal medicines analysis was performed based on the fact that he took herbal medicine two months ago, and he could finally be diagnosed with lead poisoning. Since the serum lead level was high enough to be indicated for lead chelating therapy, conservative management was given. When a patient with toxic hepatitis due to herbal medication presents with abdominal pain, the possibility of lead poisoning should always be taken into consideration.

Abstract
OBJECTIVE To evaluate the effect of aqueous seed extract of Solanum surattense (S. surattense) on the oxidative potential of cauda epididymal spermatozoa. METHODS S. surattense seed extract was orally administered at the dosage of 10 mg/kg b.w. for 15 days, after which aspartate transferase (AST), alanine transferase (ALT), glutamate dehydrogenase (GDH), citric acid and iso-citrate dehydrogenase (ICDH) were assayed. RESULTS The activity levels of the enzymes AST and ALT, which are considered to be the androgenicity in the sperm suspension, were depleted in the extract fed rats. The activity level of the enzyme ICDH, was reduced significantly in the treated group (P<0.001). CONCLUSIONS It can be concluded that the oral administration of the aqueous seed extract of S. surattense can deplete the oxidative stress of cauda epididymal spermatozoa in albino rats.

Abstract
OBJECTIVE To investigate the expression of sonic hedgehog (Shh) signaling pathway in liver fluorosis and to explore related mechanism. METHODS To establish animal model, 48 normal SD rats (aged 4-5 weeks) were randomly divided into 4 groups (12 each): control group, fluoriosis group, blocking group and blocking control group. After 6 months, the blocking group and blocking control group were injected intraperitoneally once every 2 days for 3 times with 10 mg/kg cyclopamine or dimethysulfoxide, respectively. Rats were sacrificed at the end of the experiment and the fluoride content in urine and liver function was determined. The expression of Shh and Gli1 protein and mRNA in hepatocytes was detected by immunohistochemistry and real-time fluorescence quantitative PCR, respectively. RESULTS The fluoride contents in the urine and the incidence of dental fluorosis increased in the fluoride and blocking control groups as compared with those in the control group, but decreased in the blocking group compared with those of the fluoride and blocking control group. Compared with the control group, the titers of aspartate transaminase (AST) and alanine transaminase (ALT) significantly increased, while the activity of total protein and albumin decreased in the fluoride and blocking control groups. Compared with the fluoride and blocking control groups, the activity of the ALT slightly declined and the AST, total protein and albumin slightly increased in the blocking group. Histologically, the cells were disorganized and swollen with cytoplasmic clearing (balloon cells), compared with the control group. The expression of Shh and Gli1 significantly increased in all but the control group. Compared with the fluoride and blocking control groups, the expression of Shh and Gli1 declined in the blocking group. CONCLUSIONS The overexpression and cyclopamine inhibition of the Shh signaling pathway are closely related to the content of fluoride in the liver. The Shh signaling pathway plays an important role in the pathogenesis of liver injury caused by fluorosis, suggesting a preventive and therapeutic target of the disease.

Abstract
BACKGROUND Non-alcoholic steatohepatitis is a growing public health problem with no approved therapy; as cytokines and other pro-inflammatory mediators may each play a role in transition of steatosis to NASH which is projected to be the leading cause of liver transplantation in the United States by 2020. OBJECTIVE The aim of this study was to compare the impact of aerobic versus resisted exercise training on inflammatory cytokines and markers of liver function in patients with nonalcoholic steatohepatitis. MATERIAL AND METHODS Fifty patients with NASH were included in the study and divided into two subgroups. Participants were included into 2 equal groups; the first group (A) received aerobic exercise training. The second group (B) received resisted exercise training three times a week for 3 months. RESULTS The mean values of TNF- α, IL6, IL8, ALT and AST were significantly decreased in group (A) and group (B). Also; there was a significant difference between both groups after treatment. CONCLUSION Aerobic exercise training modulates inflammatory cytokine levels and markers of liver function in patients with nonalcoholic steatohepatitis.

Abstract
Chronic hepatitis C (CHC) affects around 16,000 individuals in Denmark of whom about 50% are diagnosed. In the presence of CHC and cirrhosis the annual risk of hepatocellular carcinoma (HCC) is 1-5%. We report on two patients who presented with disseminated HCC at the time of CHC diagnosis. At the time of diagnosis only non-curative treatment was available. An earlier diagnosis of CHC could potentially have led to a cure and prevention of HCC.

Abstract
The observational study was aimed at assessing the effectiveness and tolerability of Heptral (brand of ademetionine 1,4-butane disulfonate) in Indian patients presenting with intrahepatic cholestasis (IHC) due to chronic Non alcoholic liver disease (NALD). The study also aimed at understanding the prescribing practices of physicians as well as the profile of patients being prescribed Heptral. This Prospective observational study included 250 patients across 23 sites in India. The assessments of health-economic parameters, liver biochemistry, signs and symptoms of IHC (fatigue, jaundice, and pruritus) were performed at two visits, i.e., at baseline and after six weeks of Ademetionine treatment. Ademetionine was prescribed as part of the routine medical treatment as per the local label and not as a study intervention. Full analysis set (FAS) population included 244 patients. The mean age was 43.75 +/- 11.14 years and 75.5% (184/244) patients were males. 30.7% (75/244) of FAS population presented with cirrhosis. Concomitant medications were recommended to 44.4% (108/243) patients. Ademetionine treatment resulted in statistically significant reduction (p < 0.0001) in burden of disease parameters (number of days off work and number of visits to doctor), levels of biochemical markers and signs and symptoms of IHC. Physicians had favourable opinion for effectiveness and tolerability of Ademetionine for majority of the patients. Administration of Heptral in patients with NALD and IHC resulted in significant improvement in burden of disease, laboratory markers, signs and symptoms of cholestasis. The treatment was well tolerated.

Abstract
AIM The aim of the present investigation was to analyse cephalometric skeletal structures and hormonal and enzymatic parameters in young obese subjects in comparison with those of normal weight subjects. MATERIALS AND METHODS The whole sample consisted of 50 Caucasian patients (28 males and 22 females) whose lateral radiographs, laboratory hormonal and enzymatic analyses were already available. The test group included 25 obese patients (11 females and 14 males, average age: 9.8 +/- 2.11 years old), while the control group included 25 normal weight subjects matched for age and sex (11 females and 14 males, 9.9 +/- 2.5 years old). Data were statistically analysed: Student's t-test for independent samples was adopted and the level of significance was set at: p < 0.05. RESULTS As regards cephalometric records, the anterior cranial base length was significantly greater in the test group (S-N: 69.9 +/- 4 mm) compared to the controls (S-N: 68.1 +/-2.7 mm). Moreover, the maxillary lenght was higher in the test group (Pm-A: 48.5 +/- 2.5 mm) in comparison to the control group (Pm-A: 46.1 +/- 1.9 mm). As regards skeletal class and vertical dimension, no significant differences were found between the two groups, with the exception of the intermaxillary plane angle, which was significantly lower in the obese subjects in comparison to the controls. Laboratory analysis showed significant (p < 0.05) higher levels of leptin and insulin in the test group in comparison with control subjects. Furthermore, LH, FSH, IGF-1 values were significantly (p < 0.05) lower in the test group in comparison with the control group. CONCLUSION Obese subjects exhibited an increase of some craniofacial parameters and alteration of some laboratory parameters that may be involved in the process of skeletal maturation, in comparison to normal weight subjects. These findings may be of interest in orthodontics, as young obese subjects may need a different orthodontic treatment plan in comparison to normal weight subjects of the same age.

Abstract
Although sulfite (SO3(2-)) is commonly used as an antimicrobial agent and preservative in foods, medicines and wine, it has also been listed as an important risk factor for the initiation and progression of liver diseases due to oxidative damage. In general, apoptosis that is induced by oxidative stress is triggered by increases in p53 and alterations in Mdm2 and Bcl-2. However, the level of involvement of the p53 signaling pathway, which has been shown to be upregulated in some animal studies, in hepatocyte death remains unclear. To examine the response of the p53 signaling pathway to stimulation with different concentrations of sulfite, a time course study of p53, Mdm2, and Bcl-2 expression was conducted in an immortalized hepatic cell line, HL-7702. When the HL-7702 cells were cultured in the presence of Na2SO3, the cell viability was significantly decreased after 24h compared to that of the control group (0mmol/L) (p<0.05). Meanwhile, aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels in the supernatants of HL-7702 cells were significantly increased following Na2SO3 administration. Interestingly, the expression of p53 and p-p53 (Ser15) remained unchanged. In addition, no obvious alterations in Mdm2 and Bcl-2 expression were observed in HL-7702 cells that had been stimulated with various concentrations of sulfite. To further investigate the detailed mechanism underlying sulfite toxicity, caspase-3, PCNA and RIP1 expression in HL-7702 cells was studied. The expression levels of caspase-3 and PCNA were unchanged, but RIP1 expression was increased significantly after 24h of exposure. In light of this evidence, we propose that sulfite is cytotoxic to hepatocytes, but this cytotoxicity is not achieved by direct interruption of the p53 signaling pathway. In addition, we propose that an alternative necrotic process underlies hepatocellular death following sulfite exposure.
